92-1210 Twin Cam 106" big bore piston kit. Std

This S&S big bore piston kit is designed for 1999 to 2006 88-inch Twin Cam engines that have been upgraded with 4-1/2 inch stroker flywheels and 3-7/8 inch bored cylinders. This combination results in a 106-inch displacement with a 9.7:1 compression ratio when using stock heads. Sold as a set, these forged flat-top pistons are engineered to be the same weight as stock pistons, meaning no crankcase re-balancing is required. They are compatible with both stock and S&S cylinder heads and come complete with rings, wrist pins, and clips. This kit is also the standard replacement for S&S 106-inch Hot Set-Up kits. It is a robust choice for riders looking to maximize the potential of their early Twin Cam motor.
